PATENT 0mm v WILLIAM WAKELEY, OF HOMER, NEW YORK.

METAL DRILL.

Specification of Letters Patent No.

T 0 all whom it may concern Be it known that I, WILLIAM WAKELEY, of Homer, in the county of Cortland and State of New York, have invented a new and useful Improvement in Self Feeding Metal Drills for Boring Metal; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1,-is a side elevation of my improved drill. Fig. 2, is a vertical longitudinal section of the same through its center. Fig. 3, is an end elevation. Fig. 4, is a face view of one of the feed wheels, showing the manner in which it is made in sections.

Similar letters of reference in each of the several figures indicate corresponding parts.

.This invention relates to an improvement in the common blacksmiths drill, whereby its construction is simplified, and it rendered capable, when turned to the right, of feeding forward very rapidly, as it revolves,

until it comes in contact with the metal to be bored, and then of being arranged and adjusted with great ease and facility, so that it shall continue its feed forward in a slow and gradual manner until the metal is bored through, and then again of being adjusted,

so that it shall, when turned to the left, move rapidly back to its original position, ready for another operation.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, represents the metal standard or support for the drill.

B, B, is the drill stock divided transversely at a, it passes horizontally through the standard A, and is provided with a screw thread B which works in a female screw cut in the standard A, as shown.

C, is a spur wheel secured fast on the outer end of the part B, of the stock;

D, is the drill spindle; its inner end has the part B, (of the stock,) which carries the drill E, secured fast to it, and on its outer end, the crank by which the drill is turned, is also secured fastf F, is a pinion secured tight on a rod 12, passing horizontally through-the barrel 0, of the handle G, of the crank, and revolving freely in the same. I

It is by making the drill stock in two parts B, B, and providing the part B, with a 12,010, dated November 28, 18 54.

screw thread B on one end, and spur wheel on the other, and having the pinion work in the spur wheel C, that a rapid forward movement or feed, when the crank is turned to the right, of the drill is secured simultaneous with its rapid revolving movement and vice versa when the crank is turned to the left.

H, is another spur wheel arranged loosely on the stock, and so near the spur wheel C,

that it nearly touches its inner face as shown.

0 is a stop or pin for preventing the wheel H', revolving; it is secured in the wheel H, and passes and works loosely in a hole (Z, ,cut in the standard A, as the drill moves back and forth.

Te spur wheel H, has less teeth than the spur wheel Cfor instance H, having 93, andC, 96, teeth. The pinion is made capa ble of gearing into both of these wheels at once or separately, as occasion may require, by making it of an increased width, and arranging it on the revolving rod 6, which is capable of sliding back and forth as illustrated in red in the drawings. It is by employing the loose stationary wheel having 93 teeth, in combination with the revolving wheel which has 96 teeth, and having the pinion E, gear into them, as shown by red lines in Fig. 2, that the drill, after it has been fed rapidly up to the metal, is fed slowly and gradually through the same, for it will be seen that by giving the wheel C, three more teeth than the wheel H, the drill will be fed forward by the screw the distance of three teeth at every revolution it makes. It, should be kept in mind that the wheel with 96 teeth, revolves, and is also fast on the part B, of the stock which has the screw thread cut on it, and consequently, whenever the pinion gears with both of the wheels C, and H, at once, the clrillwill be fed slowly and regularly forward.

The handle of the crank is made in two parts, G, g, 9 being secured fast by a nut on the square part of the rod 7), and G, loosely on the round, part of the same by a collar 2', which is confined and made to bear against the shoulder of the rod 6. By this arrangement, the part 9, is allowed to turn with the rod 79, independent of the part G; and when the handle is moved in or out, both parts will move together and the pinion F, consequently can be moved into or out of gear without the necessity of the workman taking his hand ofl' the part Gr, and applying it to g. V

To avoid the necessity of removing the wheels H, C, when it is desired to change the feed, I make H, in three sections h, 71,, h, and put it together by screws, as shown in Figs. 3 and 4. By thus making the wheel in sections, several changes in the feed can be made with great facility; for by taking away eit-hervof the sections 71, and inserting in its place a section having a greater number of teeth, the amount of feed will be decreased, and by putting in a section with a lesser number of teeth, the amount of feed will be increased.

I do not claim making met-a1 drills capable of self feeding, by employing two wheels, C, H; one provided with a greater, and the other with a lesser number of teeth, as an equivalent device has already been employed in ratchet drills for boring metal, but

I claim 1. Providing the crank with asliding handle, and arranging the pinion F, on the same, so that it may be thrown into gear with one or both of thewheels C, H, as oocasion may require, substantially as, and for the purposes set forth.

2. I also claim the arrangement and combination of the pinion F, spur wheels C, H, and drill stock B, when provided with a screw B substantially as and for the purposes set forth. 7

3. I likewise claim for the purpose of facilitating the change in the feed of this particular drill the making of the wheel in sections and the substitution of a section having a greater number of teeth for one having a lesser number substantially as described.
